Products: Citrix Access Essentials 1.0, Web Interface for Presentation Server 4.0

Symptoms

Automatic deployment of the Win32 Presentation Server Client fails for Windows XP Service Pack 2 clients if the web server is not in the Trusted Sites or Intranet zone.

Cause

When Web Interface 4.0 or Citrix Access Essentials is configured to “Automatically update the Web client at log on,” Windows XP Service Pack 2 clients that do not trust the Web server will receive the Internet Explorer “Information bar” telling them that an ActiveX control is available for download. But if they click the information bar and select “Install ActiveX control,” nothing happens.

Resolution

Either of the following actions may be used to resolve this issue:

• On the client machine, add the Web Interface or Citrix Access Essentials server URL to the Internet Explorer Trusted Sites zone.

-OR-

• On the Web server, edit the file Win32WebClientDownload.aspx and remove line 21 which reads setAutoDeployDone( true );. Save the file and changes take effect immediately.

The Win32WebClientDownload.aspx file may be found at the following locations.

For Web Interface 4.x sites:

/site/Win32WebClientDownload.aspx, where refers to the document root of the Web Interface site. For example, C:\Inetpub\wwwroot\Citrix\MetaFrame\site\Win32WebClientDownload.aspx

For Citrix Access Essentials (Internal site):

C:\Inetpub\wwwroot\CitrixAccess\site\Win32WebClientDownload.aspx

For Citrix Access Essentials (External site):
